Historical Source and Enlightenment of Keynesian Economics Running away from Home:On the Essence of Credit Money and Positive Significance of Financial Derivatives
Since the 20th century,the common nostalgia complex in Britain is a reflection of conserva-tism,which has greatly hindered the social elites'cognition of the nature of credit money and its practical significance,as well as their acceptance of the economic theory of government intervention.The"backslid-ing"of conservative politicians who determined to return to the gold standard currency and fiscal balance led to the decline of Britain after the two world wars.Some prominent economists such as Pigou and Robbins forced Keynesian theory to lose its real influence on the British economy.But Roosevelt's New Deal and the stable status of Wall Street as an international financial center led to the running away of Keynesian monetary theory from her home like a cheating lover and finding a social basis to flourish in the United States.Flourishing complex and hegemonism are a reflection of nostalgia complex.Financial deriva-tives are the most essential and typical capital characteristic of credit economy.The original sin of financial crisis is not financial derivatives,but the lack of effective supervision by the government.Decomposing op-erational risks through financial derivatives and promoting digital currency to strengthen credit are realities that must be dealt with in a socialist market economy.
